Researchers have uncovered evidence that superconductivity can be controlled by changing a material's surrounding environment, a breakthrough that could eventually lead to more efficient electronics and powerful quantum technologies.
Superconductivity allows certain materials to carry electricity with zero energy loss when cooled below a critical temperature. Even though scientists have studied the phenomenon for decades, many of its underlying mechanisms remain poorly understood. Gaining deeper insight into how superconductivity forms could help researchers design better materials and improve future electronic and quantum devices.
Twisted Graphene Reveals Unusual Behavior
The study, led by Chun Ning (Jeanie) Lau, a physics professor at The Ohio State University, focused on a specially engineered material known as twisted bilayer graphene. The material is made by stacking two sheets of carbon and rotating one slightly relative to the other.
The research team combined the graphene structure with strontium titanate, a synthetic diamond-like material. This setup allowed scientists to observe and influence how electrons interacted inside the system.
